<p>Path of a tag in the Subversion repository using a build name.
The path is computed relatively to the root of the repository.</p>
<p>The <code>{build}</code> placeholder is used  to define the location where
to replace the path fragment by the build name. An optional expression can follow
the build keyword: <code>{build:expression}</code>. In this case  the build name
must match the expression, where <code>*</code> stands for any suite of characters.
For example: <code>{build:2.7.*}</code> will match <code>build 2.7.0-15</code>,
but not <code>2.8.0</code>.</p>
